  • a/c fan coil units

    I am wondering about the proper way to size supply and return piping for the installation of Carrier 42ck fan coil a/c units. I have the york manual and I also have the carrier guide and it gives an excellent formula for doing so however I am confused on the true way of finding hydrostatic lift of the cooling tower and also do the pipes need to be pitched at all. I am also wondering if there are high pressure valves available due to the high operating pressure of the system and if so, where can I buy them. Thank you very much for your time.
